Semantic Model & Dataflow refresh error visible directly in workspace

[SEMattis]

Currently, when a Semantic Model or Dataflow is failing a user only sees a triangle with an exclamation mark which notifies the user something has gone wrong. Instead of just warning the user that something has gone wrong it would be a good feature to actually show what the latest refresh error was caused by.

I've created an idea to implement a feature (See link below) that would allow for faster debugging since the proposal is to show the latest error immediately in the workspace rather than having to click on the error symbol and downloading the file for an extensive report.
